Detection is made either after power on or by button “Scan for new sensors”. All found sensors
are shown in ascending order refer their unique ID number.
For every sensor, there are a description, value, and ID information.
Teracom 1-Wire sensors readings are shown in the Value 1 column. Dual sensors such as the
(TSH2xx) temperature/humidity sensors have the 2nd parameter shown in the Value 2 column.
It is possible to lock sensors in a specific position. To do this all sensors should be added one by
one. After every addition, a new scan should be made and newly found sensor should be locked in
its position. If
all sensors are locked, removing one “in the middle” will not change the positions of
other sensors after reset. This option is very useful when TCW241 is used us a part of monitoring
and control system managed either by SNMP or HTTP API commands.
For som e sensors “Unit”, “Multiplier” and “Offset” can be set in section “Setup - Input/Output”.
7.1.2. Data - digital inputs section
Digital inputs can be used for monitoring the state of discrete devices – motion sensor, door
contact, relay contact, alarm output etc. All digital inputs are not galvanic isolated.
One side of the contact is c onnected to “Digital In” and another side is connected to “GND” pins.
Digital inputs are sampled every 10mS. The change of input status is considered valid if the same
value is read in 3 consecutive samples (30mS) and low-to-high/high-to-low delays
(Setup->Conditions) are zero.
Status of every input is shown by text and by color. The color is red if the input is in an alarm
condition.
